Blockchain based Content Sharing Management in VANETs - 2021

Blockchain based Content Sharing Management in VANETs

Research Area:  Vehicular Ad Hoc Networks


In the vehicular ad hoc networks (VANETs), vehicles share content with other vehicles and roadside units (RSU) to improve traffic efficiency. However, the vehicles and RSUs are not always credible. If they have malicious behavior, sharing false information put lives in danger. To address these security challenges, we propose a content sharing management method based on blockchain in VANETs. Specifically, we propose a hybrid trust model to evaluate the credibility of content based on the vehicle entity and interactive data. We deploy practical Byzantine fault tolerates (PBFT) consensus protocol based on the interaction frequency between RSUs and vehicles. The higher the interaction frequency, the more likely the RSU is to gain the right to package the block. In this way, RSUs and vehicles actively participate in the network, and achieve the content sharing honestly and effectively. We conduct extensive experiments, which demonstrate the implementation feasibility of proposed mechanisms.
